Watch all Tarantino movies. Reservoir Dogs, Pulp Fiction, Jackie Brown, Kill Bill (V1-V2), Death Proof (Imo, his worst film, not all bad, just not good), Django:Unchained (IMO, the best), Hateful 8, Once Upon a Time in Hollywood.

You should probably also watch his script movies, True Romance and Natural Born Killers, Dusk till Dawn, these are both written by Tarantino, True Romance is probably the best and most similar to Tarantino in style
